Description

technical field

[0001] The present invention relates to the field of computer technology, in particular to a data processing method, device and computer readable medium. Background technique

[0002] The multiplication and addition operation (a*b+c) has been widely used in the engineering field. For example, the convolution operation in digital signal processing is composed of a series of multiplication and addition operations. With the continuous development and application of artificial intelligence technology, a series of algorithms represented by artificial neural networks have put forward new requirements for point multiplication operations. However, the multiplication and addition operation is the basic operation of the dot multiplication operation, and its requirements for the multiplication and addition operation are also increased.

[0003] At present, in order to realize the multi-input multiply-accumulate operation in various application-specific integrated circu...
